Abstract:
The main aim of this study is to compare the information about meiosis and mitosis
divisions of secondary school students with different methods. The mixed method was
used in the research. In the mixed method, it is aimed to close the deficiencies in the
solution of the research problems with both qualitative and quantitative data.
Homogeneous samples were used in the study. In the 2018-2019 academic years, it was
conducted with 7th grade students in a public school in Eastern Anatolia. A total of 132
students participated in the study, depending on the volunteerism principle. Matching
test was used to collect quantitative data. Qualitative data were collected through a
fully structured interview form. The collected data were analyzed with the help of
Microsoft Excel program. Descriptive and content analyzes and techniques such as
frequency and percentage values were used. According to the findings, the knowledge
of meiosis and mitotic divisions was found to be good level. It was determined that
most of the students had the right information about meiosis and mitosis and they
knew the general characteristics of these divisions. According to these findings of the
study, concordant results were obtained by using mixed method with different
measuring methods. Suggestions are presented in parallel with these findings.
Keywords: science, meiosis and mitosis divisions, knowledge level, mixed method
1. Introduction
The science course is a science that allows us to understand nature and natural
phenomena. In this science, the researcher tries to understand the natural world and its
diversity by using the feelings of doubt and curiosity with its explorer and interrogator
identity (Çaycı, 2007; Doğru and Kıyıcı, 2005).One of the basic aims of the science is to
use the knowledge acquired by the individual (Zeidler, Sadler, Simmons and Howes,
2005). Individual should be able to use the knowledge gained in science subjects in

daily life (Sadler and Ziedler, 2009). Thanks to this science, knowledge about the living
universe, living things, physical and chemical events is learned. Another subject learned
is cell division. These subjects, known as meiosis and mitosis divisions, are learned at
seventh grade level in secondary school. The main purpose of these subjects is to get
information about students' concepts and daily use (MoNE, 2018).
There are difficulties in education due to reasons such as abstracting and not
reaching the science concepts. Very abstract concepts prevent students from learning
this lesson in a meaningful way (Bora, Çakıroğlu and Tekkaya, 2006). The subject of cell
divisions is also the subject of learning difficulties (Demirkuş, 2019). The most obvious
reason for this is the adaptation of the words of foreign origin to the Turkish language
(Demirkuş, Ertas and Gulen, 2018). Although there are difficulties in teach these
subjects (Atılboz, 2004), new approaches and methods should be applied in teaching
subjects. For example, it is thought that it will be possible to eliminate the possible
difficulties with the material and to get knowledge (Sinan and Karadeniz, 2010).
Knowledge can be defined as a whole of learned facts about any subject. As a
matter of fact, human beings learn something from birth (Güven, 2014). The area of
knowledge is quite high. Technology, science and education are just some of these areas
(Brillouin, 2013). The main purpose of the knowledge acquired in science education is to
provide the satisfaction of the individual and to use this information. As a matter of
fact, the information obtained about cell divisions should be close to daily life and
should be available (Baran, Doğan and Yalçın, 2002; Demiral and Türkmenoğlu, 2018).
Meiosis and mitosis and related concepts should be learned in a meaningful way
(Daşdemir and Doymuş, 2012). The aim is not to memorize the information is to think
of learning (Aydin and Balim, 2013).
Students will have to think about the meiosis and mitosis divisions and try to use
them in their daily lives. Mitosis in general; it allows proliferation in single-celled
organisms, growth and repair in multicellular organisms. At the end of the mitosis
division, the number of chromosomes remained constant and consisted of 2 new cells.
The resulting cells are inherently identical. This division occurs in the body cells
(MoNE, 2018; Özdemir, 2006). Meiosis only occurs in the genitals. By dividing meiosis
of the main reproductive cells, the number of chromosomes consists of four new cells
that are halved. The cells formed are different from each other in hereditary way
(Akyürek and Afacan, 2012; MoNE, 2018). Both quantitative and qualitative methods
are used to determine students' knowledge about meiosis and mitosis. In addition, a
mixed method is formed by the application of these two methods together.
The mixed method is to collect and integrate both qualitative and quantitative
data to understand the research problem (Creswell, 2017). The aim of this method is to
close the missing aspects of qualitative and quantitative methods while seeking a
solution to the research problem. These results are obtained more objectively (Creswell
and Plano Clark, 2011). In addition, quantitative results are supported with answers to
questions such as how and why the qualitative results are supported with statistical
data (Yıldırım and Şimşek, 2013). The most important situation here is the adaptation of
the data obtained by both methods. As a matter of fact, a definitive judgment is reached

through this harmony. When the literature is examined, it can be said that the mixed
method studies are increasing (Bellibaş and Gedik, 2014; Demirci, 2017; Evren
Yapıcıoğlu and Kaptan, 2018; Kalman and Summak, 2016; Kocaman-Karoğlu, 2015). But
the results of these studies should be examined. In addition, students are known to
suffer from various cell divisions (Tekkaya, Çapa and Yılmaz, 2000; Tekkaya, Özkan
and Sungur, 2001). What are the levels of knowledge of students about cell divisions?
Are similar results achieved when different methods are used? Are these results
consistent with each other? The answer to such questions was sought. Therefore, it is
important to determine the knowledge level of the students about meiosis and mitosis
in the research by means of a mixed method and to obtain the data which are integrated
by comparing the qualitative-quantitative data.
1.1 Purpose of the research
The main aim of this research is to compare the information about meiosis and mitosis
divisions of secondary school students with different methods. In this context, the
answers to the following questions were sought.
1) What is the level of knowledge of secondary school seventh grade students'
about meiosis and mitosis divisions?
2) What is the similarity level of secondary school seventh grade students' level of
knowledge about meiosis and mitosis divisions?
2. Method
The mixed method was used in the research. In the mixed method, it is aimed to close
the deficiencies in the solution of research problems with both qualitative and
quantitative data (Büyüköztürk, 2009; Çepni, 2010; Yıldırım and Şimşek, 2013).
Qualitative data were collected together with quantitative data.
2.1 Participants
Homogeneous (analogous) samples were used in the study. The aim in the analogous
sample is to determine the status of groups of similar characteristics in a subject in
order to collect the data effectively (Creswell, 2013). As a matter of fact, the research
was conducted with 7th grade students in a public school in Eastern Anatolia Region
during the 2018-2019 academic years. A total of 132 students participated in the study,
depending on the volunteerism principle. While all students participated in the
matching test used in the study, 100 students participated in the fully structured
interview form. 27 students were not allowed to leave the form blank and 5 students
could not read the forms. The socio-economic status of the participants was similar. The
families of the majority of the participants are engaged in farming. Farming means a
small number of agriculture and animal care. They also conducted research on mitosis
and meiosis divisions at the beginning of the 2018-2019 academic years. This topic has
been discussed and learned in class.

2.2 Data collection tools
Matching test was used to collect quantitative data. This test measures students'
concepts of mitosis and meiosis and their correct mapping of properties and
relationships. Qualitative data were collected through a fully structured interview form.
In the fully structured interview form, the following questions were used.
1) Why is mitosis division important for living things?
2) Why is meiosis division important for living beings?
2.3 Analysis of data
The data of the measurement tools used in the study were analyzed with the help of
Microsoft Excel program. Descriptive and content analyzes and techniques such as
frequency and percentage values were used.
In each pairing test, each line was evaluated as 1 point. In total 16 matches are
required. These notes were then converted into a hundred percent note system.
The data of the fully structured interview form were analyzed both in terms of
descriptive and content in order to determine information about mitosis and meiosis
divisions. The data obtained by the two analysis methods are presented in the findings
section.
The score range of the matching test was evaluated according to the criteria
given in Table 1.
Table 1: Interpretation value range of scores
Order Value Range for matching test
1 Very bad 00.01 - 20
2 Bad 20.01 - 40
3 Middle 40.01 - 60
4 Good 60.01 - 80
5 Very good 80.01 - 100
As seen in Table 3, five equal intervals were determined for more precise interpretation.
According to this, it is very bad, bad, middle, good and very good value for true-false
test. Kandemir (2015) has similar criteria to this table in his study.
2.4 Reliability and Validity
Within the scope of the reliability studies, the status of the sample group was explained
in detail, the existing roles were explained, the conceptual framework and data
collection and analysis were presented. In addition, these data were supported by
descriptive analysis and content analysis (Glesne, 2013). The fully structured interview
form used is based on expert opinion. The analyzed received help from their teachers.
For the coding and scoring, reliability was calculated using the formula of Miles and
Huberman (1994). According to this calculation, 95% confidence coding was performed
throughout the study. In fact, according to Miles and Huberman (1994) 80% and above
has been accepted as reliable (Arik and Yilmaz, 2017). In the descriptive and content

European Journal of Education Studies - Volume 5 │ Issue 10 │ 2019 212
analysis of validity of the research, direct quotations were given and the accuracy of the
research results was shown (Merriam, 2013). The codes used in the content analysis and
the interpretations were done in depth. The names of the participants are coded. In
addition, subject gains were taken into consideration in terms of the scope validity of
the matching test. Validity values such as structure and appearance are obtained by
taking expert opinion (Yıldırım and Şimşek, 2013).
3. Results
The data collected with both qualitative and quantitative measurement tools are
presented below. As a result of the evaluation of the matching test used in the study,
the values given in Table 2 are obtained.
Table 2: Matching test statistical values
Test N Standard deviation Average Comment
Matching test 132 24.12 63.26 Good
Table 2 shows the mean and standard deviation of the scores of the students who took
part in the matching test. In addition, these average scores are “good” level within the
scope of the criteria in Table 1. According to this, the mean score of the participants was
63.26 and the standard deviation was 24.12.
The data obtained as a result of the fully structured interview form analysis used
in the research are presented below. The most commonly used expression as a result of
the descriptive analysis is given in Table 3.
Table 3: Most repetitive expressions
Order Expressions (N: 100) Frequency (f) Percent (%)
1 Mitosis provides reproduction in single cells 60 60
2 Meiosis provides reproduction in multiple cells 51 51
3 Mitosis makes repair 37 37
4 Mitosis provides growth and development 31 31
5 Meiosis provides hereditary diversity 28 28
As shown in Table 3, the first three of the most repetitive statements “mitosis provides
reproduction in single cells”, “meiosis provides reproduction in multiple cells” and
“mitosis makes repair”. In general, it is observed that the majority of participants use
correct expressions about meiosis and mitosis. As a matter of fact, it is seen that 60% of
the respondents said that mitosis divides single-celled animals, 37% of them provide
mitosis and 31% of them show mitosis growth and development. These statements are
generally used by different participants. Similarly, it was seen that 51% of the
participants stated that meiosis divergence in multicellular organisms and that 28% of
the meiosis division provided hereditary diversity. The sum of these two data is above
average. Based on these data, it is seen that the majority of the participants have
sufficient knowledge about meiosis and mitosis divisions. It is understood that most of

the new participants have at least one or more accurate knowledge about meiosis and
mitosis divisions.
In addition to the descriptive analysis, the themes and categories obtained in the
content analysis are presented below.
3.1 Recognition of meiosis and mitosis divisions
Under this theme, the quotations of the participants were analyzed with the two
categories mentioned below.
A. Meiosis division
The statements used by the participants in this category are quoted below (Quotes are
selected at random):
‚As meiosis divides in parts, it occurs in different gene structures (Cells). Hereditary
diversity is achieved.‛ (P5)
‚Meiosis provides a continuation of a generation. Provides hereditary diversity. In short,
the continuity of generation.‛ (P13)
‚As a result of meiosis, four new cells are formed. (P57)
‚It is important to keep a constant value of the number of chromosomes. Because it
usually provides reproduction.‛ (P77)
‚There is a need for meiosis in order for human beings to breed and continue their
generation. Thanks to meiotic cleavage, diversity of species is ensured and thus everyone
is different‛ (P88)
‚The part change is visible. It provides reproduction in multicellular organisms.‛ (P123)
As it is understood from the above quotations, it has been stated that “growth
occurs” with the formation of “new cells” that provide “continuity of the generation” of
meiosis. In addition, it is stated that different individuals are formed by providing the
“hereditary diversity” within the “species” by the “exchange” of parts in the meiosis
division. It can be said that the participants know the general characteristics of meiosis.
B. Mitosis division
The statements used by the participants in this category are quoted below (Quotations
randomly selected):
‚Without mitosis, single-celled organisms would not have the ability to reproduce.
Multicellular organisms cannot develop. For example, when our arm was injured, the
wound would never be healed.‛ (P9)
Salih Gülen

‚Mitosis results in two cells. Mitosis improves proliferation in single cells, healing
wounds in multiple cells.‛ (P21)
‚Repair when injury occurs.‛ (P47)
‚For some living things, reproduction provides repair and growth in some living things.
So it is important‛. (P65)
‚Mitosis division is all over our lives. For example, it allows our wounds to heal. It is
very important in our growth and development‛. (P100)
‚In order for multicellular organisms to survive, it is important for single-celled
organisms to sustain their lineage‛ (111)
As it is understood from the quotations, it is stated that mitosis division provides
“reproduction” in “single-celled” organisms, “growth and development” in “multicellular”
organisms. It has also been reported that mitosis divides makes “repair” the wounds. It
can be said that participants from these quotations know the general characteristics of
mitosis.
Apart from the above quotations, it can be said that very few participants mixed
the properties of meiosis and mitosis. Apart from these two interesting quotations are
presented below.
‚Meiosis is mating‛. (P61)
‚Meiosis and mitosis are for animals‛. (P118)
As it is understood from these quotations, although there are very few, there are
some misconceptions about meiosis and mitosis. In general, when all the citations are
examined, it was determined that the majority of the participants had the true
information about meiosis and mitosis divisions. It was also determined that the
participants knew the general characteristics of meiosis and mitosis.
4. Discussion
The average of the scores obtained from the matching test shows that the information
about meiosis and mitosis divisions is at a good level considering the criteria in Table 1.
According to this, the students are well aware of the concepts, concepts and mappings
of meiosis and mitosis. The first three of the most repetitive statements based on the
descriptive analysis of the results of the fully structured interview form; mitosis
provides reproduction in single cells, meiosis is the expression that makes reproduction
in multi-celled and mitosis makes repair. These expressions show that the students
know the basic purpose of mitosis and meiosis. As a result of content analysis, it was
Salih Gülen

determined that most of the students had the right information about meiosis and
mitosis divisions. It was also determined that the participants knew the general
characteristics of meiosis and mitosis. According to these findings, it can be said that
both qualitative and quantitative data show the same results. Compatible results were
obtained by using mixed method with different measuring methods.
Similar to the results of the study, Özdemir (2006) found that both qualitative
and quantitative methods were used in the structuring of knowledge. Kalman and
Summak (2016) had positive results in experimental study with teachers using the
mixed method. Also, Kocaman-Karoğlu (2015) according to his work in scientific
research is increasing the rate of use of mixed methods. It is present in studies that do
not show similarity with the results of the research. Evren Yapıcıoğlu and Kaptan (2018)
found that some of the qualitative and quantitative data were not compatible with each
other. Although Bellibaş and Gedik (2014) and Demirci (2017) used mixed methods in
their studies, they found discrepancies between qualitative and quantitative data. In
addition to these studies, Bakırcı, Artun, Şahin and Sağdıç (2018) have determined that
students can use the information they have learned in their daily life problems. Wersig
(1993) also stated that it is important to pay attention to the teaching of familiar and
common concepts. As a matter of fact, meiosis and mitosis divisions are both related to
daily life and should be considered. In addition to the above studies, there are various
problems in students' cell divisions (Emre and Bahşi, 2006; Tekkaya, Çapa and Yılmaz,
2000; Tekkaya, Özkan and Sungur, 2001). Although this study is rare, attention should
be paid to the teaching of cell division issues.
4.1 Conclusions and recommendations
The knowledge of students about meiosis and mitosis divisions was found to be good
level. It is suggested that the level of knowledge in a subject can be determined using
the matching test.
It was determined that most of the students had the right information about
meiosis and mitosis and they knew the general characteristics of these divisions.
Furthermore, it was determined that they knew the basic purpose of mitosis and
meiosis. Using a fully structured interview form, it is possible to determine what a
student knows about a subject. This is recommended for similar studies.
According to the results of this study, mixed results were obtained by using
mixed method with different measuring methods a mixed method is recommended for
studies that need to show the same result with different aspects of a subject.
